致命错误：numpy/arrayobject.h：google colab 中没有这样的文件或目录#include“numpy/arrayobject.h”

Question

hello i am trying to run a git repo in google colab, i installed all requirements as per the git instruction

while running the certain file i am getting this error

fatal error: numpy/arrayobject.h: No such file or directory
#include "numpy/arrayobject.h"

i already checked solution for this error but they recommended to change the code in setup.py but i am running the file in google colab so some body help me

the command i ran in google colab was

     !python build.py build_ext --inplace

for which i got the following error could some body help me , i verified that numpy was already installed

    running build_ext
    skipping '_nms_gpu_post.c' Cython extension (up-to-date)
    building '_nms_gpu_post' extension

Answer 1

I had a similar problem and I solved it by editing build.py :

ext_modules=[
        Extension("my_module", ["my_module.c"],
                  include_dirs=[numpy.get_include()]),
    ]

Here include_dirs=[numpy.get_include()] is the part that's needed to solve it.
